Summary
Eutectic mixture of local anesthetics (EMLA) did not prevent dyschromia after radiofrequency ablation for dermatosis papulosa nigrans. The cream was well-tolerated by participants in this study.
Area of Science:
- Dermatology
- Medical Aesthetics
Background:
- Dyschromia is a common side effect of superficial skin procedures.
- Radiofrequency (RFC) ablation is used to treat facial dermatosis papulosa nigrans (DPN).
Purpose of the Study:
- To evaluate the efficacy of eutectic mixture of local anesthetics (EMLA) in preventing dyschromia post-RFC ablation for DPN.
- To assess the tolerability of EMLA cream in patients undergoing RFC ablation.
Main Methods:
- Observer-blind, case-control study.
- 60 patients with DPN were divided into two groups.
- Group A received RFC ablation with prior EMLA application; Group B received RFC ablation without EMLA.
Main Results:
- No significant difference in dyschromia was observed between the EMLA group and the control group.
- EMLA cream was well-tolerated by all study participants.
Conclusions:
- Pre-treatment with EMLA does not appear to prevent or reduce dyschromia following RFC ablation for DPN.
- EMLA is a safe and well-tolerated option for patients undergoing this procedure.

3.1K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:23Local Anesthetics: Common Agents and Their Applications
745
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

611
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:13Local Anesthetics: Pharmacokinetics
1.1K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
930
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
